hard as nails

for fastening. (1.) Hebrew yathed, “piercing,” a peg or nail of any material (Ezek. 15:3), more especially a tent-peg (Ex. 27:19; 35:18; 38:20), with one of which Jael (q.v.) pierced the temples of Sisera (Judg. 4:21, 22). This word is also used metaphorically (Zech. 10:4) for a prince or counsellor, just as “the battle-bow” represents a warrior. (2.) Masmer, a “point,” the usual word for a nail. The words of the wise are compared to “nails fastened by the masters of assemblies” (Eccl. 12:11, A.V.). The Revised Version reads, “as nails well fastened are the words of the masters,” etc. Others (as Plumptre) read, “as nails fastened are the masters of assemblies” (comp. Isa. 22:23; Ezra 9:8). David prepared nails for the temple (1 Chr. 22:3; 2 Chr. 3:9). The nails by which our Lord was fixed to the cross are mentioned (John 20:25; Col. 2:14).

In Jer. 17:1 this word is rendered “point.”
